Rexroth Plunger Pump A10VSO71DFR/31R-PPA12KO2 Injection Molding Machine Hydraulic Pump
Product Description:
The plunger in a piston pump is also designed to withstand high pressures and abrasive fluids. This is achieved through a combination of factors, such as the use of durable materials and careful selection of plunger and cylinder sizes. The surface of the plunger is often hardened or coated with materials such as ceramic or tungsten carbide to resist wear and corrosion. In some cases, the plunger may be equipped with packing or mechanical seals to prevent fluid leakage between the plunger and cylinder. This is important because leakage can lead to reduced pump efficiency, increased maintenance costs, and potential safety hazards.
Features
Self-priming: Plunger pumps are designed to be self-priming, meaning they draw fluid into the pump without the need for additional priming equipment or processes. This makes them ideal for applications that require a steady flow of fluid.
High Pressure and Flow: Plunger pumps are able to produce high pressure and flow, making them useful in applications that require precise and efficient fluid delivery.
Versatility: Plunger pumps can be used with a wide variety of fluids, including viscous and abrasive liquids. They can also handle a wide range of temperatures and pressures, making them versatile in a range of applications.
Reliability: Plunger pumps are known for their durability and reliability, and they require minimal maintenance compared to other types of pumps.
Advantages
The axial piston fixed displacement motor is designed with an inclined shaft structure, making it particularly suitable for hydrostatic transmission in both open and closed circuits. It is ideal for use in mobile machinery and a range of industrial applications.
The output speed of the motor is directly proportional to the pump flow and its displacement. Additionally, torque increases with the pressure differential between the high and low pressure sides, as well as with a rise in displacement.
Choosing the correct displacement is crucial, as its specifications can be customized for specific applications. This motor features a high power-to-weight ratio and a compact design. It also offers starting torque, an economical configuration, and an integrated plunger system complete with a plunger ring.
